  • Question

  • Hi,

    I have 3 x SIP addresses and they are the same with SMTP email addresses.

    For example,

    1. user1@inter.com.sg

    2. user2@partner.com.sg

    3. user3@learning.com.sg

    From Skype for Business Configuration Information, user2 & user3 EWS Information are EWS not deployed.

    User1 has no problem at all.  3 x autodiscover are configured such as autodiscover.inter.com.sg, autodiscover.partner.com.sg and autodiscover.learning.com.sg and pointing to same IP address. Let's say 192.168.1.168

    From Exchange EWS, it is configured as mail.inter.com.sg and pointing to 192.168.1.168 as well.

    Have tried to modify the registry keyTrustModelData: https://support.microsoft.com/en-us/kb/2833618 but still does not work.

    Please advice.  Thanks.

    It is resolved after created SRV and pointed to autodiscover.inter.com.sg.

  • Hi Kelvin,

    Can you please verify "email" attribute of the users facing problem is same as sip address of those users.

    you can check this in Active directory, find user and properties.

    either check general tab -> E-Mail:

    or enable advanced from view menu and check Attributes tab -> email from active directory properties.

    Hope this helps

  • Hi Mvh,

    Yes, confirmed with ADUC that email attribute the SIP address are the same.

    Also, have checked 3*SRV records are in-place.

  • Hi Kelvin,

    Welcome to our forum.

    The Lync client will attempt to connect to Exchange Web Services in order to display items like Conversation History and Visual Voicemail.  If it cannot connect to EWS, it will fall back to a MAPI connection via the Outlook client.  The MAPI connection will allow chats to be deposited in the Conversation History folder and display presence information within Outlook and a few others, but the EWS connection provides a richer experience.

    Unlike Outlook, Lync does not use the Autodiscover SCP to locate EWS.  Lync relies on the Exchange Autodiscover DNS A record to be setup both internally and externally.  Assuming Autodiscover and EWS are working properly, the following are required in order for Lync to connect to EWS successfully:

    - User's SIP URI and Primary SMTP address should match
    - Autodiscover.sipdomain.com DNS A record setup internally and externally for each SIP domain supported
    - EWS Internal/External URLS accurately configured on Exchange

    If there are any questions or issues, please be free to let me know.
